    Tankii DESCRIPTION OF FECRAL ALLOYS: KD alloys, Alchrome / Aluchrome I / KD / KDS
    FeCrAl alloys are characterized by excellent oxidation resistance and very good form stability resulting in long element life.
    They are typically used in electrical heating elements in industrial furnaces and home appliances.
    FeCrAl alloys have higher service temperature than NiCr Alloys and much lower prices. But they have lower stability and flexibility, easily to be fragile after a time circle

    Cr22Al4.5Fe FeCrAl Alloy Flat /Round Bar With Good Surface Used For Electrical Heating Elements

     

    Application: 

    Heating elements for furnaces

    Heating lead-out rod for furnaces.

     

     

    Main properties and technical parameters of fe-cr-al electrothermal resistance alloy:

     

    The fe cr al electrothermal resistance alloy has the characteristics of high resistivity, low resistance temperature coefficient and high service temperature. Good corrosion resistance at high temperature, especially suitable for use in the atmosphere containing sulfur and sulfide, and low price, This alloy is an ideal heating material for industrial electric furnaces, household appliances, far-infrared devices.

     

    Main advantages and disadvantages of iron chromium and aluminum alloy series:

     

    Advantages: iron, chromium and aluminum electrothermal alloy with high service temperature, the  service temperature is up to 1400 degrees, (0Cr21A16Nb, 0Cr27A17Mo2, etc.), long service life, high surface load, good oxidation resistance, high resistivity, cheap price, etc. Disadvantages: The high temperature strength is low, with the temperature increases the alloy's plasticity also increases, the element is easily deformed, not easy to te bent and repaired.
